most efficient use of these tires.
● Use only the specified replace-
ment tires. Other tires may run
the danger of bursting at super
high speeds.
●
Brand-new tires can have a rela-
tively poor grip on certain road
surfaces until they have been
“broken in”. Therefore, it is ad-
visable before doing any
high-speed riding to ride con-
servatively for approximately
100 km (60 mi) after installing a
new tire.
●
The tires must be warmed up
before a high-speed run.
●
Always adjust the tire air pres-
sure according to the operating
conditions.

Cast wheels
To maximize the performance, durabil-
ity, and safe operation of your motorcy-
cle, note the following points regarding
the specified wheels.
●
The wheel rims should be checked
for cracks, bends, warpage or
damage before each ride. If any
damage is found, have a Yamaha
dealer replace the wheel. Do not
attempt even the smallest repair to
the wheel. A deformed or cracked
wheel must be replaced.
● The wheel should be balanced
whenever either the tire or wheel
has been changed or replaced. An
unbalanced wheel can result in
poor performance, adverse han-
dling characteristics, and a short-
ened tire life.
● Ride at moderate speeds after
changing a tire since the tire sur-
face must first be “broken in” for it
to develop its optimal characteris-
tics.
●
After repairing or replacing a tire,
tighten the valve stem nut and
locknut to the specified torques.
1. Valve stem nut
2. Valve stem locknut
